Mitsubishi Pencil Uni-ball ZENTO Standard 0.5 – Black Ink Ballpoint Pen (Set of 4)

The Mitsubishi Pencil Uni-ball ZENTO Standard 0.5 is a refined Japanese ballpoint pen designed to make everyday writing calmer, smoother, and more expressive. This 4-pen set features elegant shaft colors—Coastal, Canary, Ivory, and Mist—so you can choose a pen that matches your time, place, mood, and mindset.

At the heart of the ZENTO series is the newly developed ZENTO ink, engineered for a stress-free, soft writing experience with beautifully clean lines. Thanks to a cushioning ingredient (POA surfactant / polyoxyalkylene), friction between the ball tip and paper is significantly reduced—by approximately 40% compared to previous Uni-ball products. This results in smoother strokes, reduced hand fatigue, and stable ink flow.

ZENTO ink also actively reduces bleeding and smudging by attracting ink particles to one another, keeping lines crisp and controlled. Combined with a long rubber grip for steady handling and a shaft made from recycled materials, this pen balances comfort, performance, and sustainability.

Ideal for journaling, note-taking, studying, or quiet reflective moments, Uni-ball ZENTO transforms ordinary writing into a more mindful experience.
